6. The price of an item that cost $43 in 2010 always increases by $3 per year. The current price in dollars, P, of the item can be represented by the equation P = 3t + 10, where t is the number of years since the item was first manufactured. Which of the following best explains the meaning of the number 10 in the equation?
A. It is the price of the item in 1999.
B. It is the price of the item in 2000.
C. It is the price of the item in 2001.
D. It is the annual increase in the price of the item.
7.

8. Clark’s Rule is a formula used to determine the correct dosage of adult over-the-counter medicine a child can receive. The child’s weight, in pounds, is divided by 150, and the result is multiplied by the adult dose of the medicine. A mother needs to give her daughter acetaminophen, which has an adult dose of 1,000 milligrams. She does not know her daughter’s exact weight, but she knows the weight is between 75 and 90 pounds. Which of the following gives the range of correct dosage, d, in milligrams of acetaminophen the daughter could receive?
A. 50 < d < 60
B. 500 < d < 600
C. 1,000 < d < 1,200
D. 1,600 < d < 2,000
9. Ohm’s Law, which can be written as IR = V, relates the current I in amperes that flows through a conductive material with resistance R ohms to the voltage V between the two ends. The power P in watts can be related to I and R by the equation I = \( \sqrt[]{\frac{P}{R}} \) . Which of the following gives P in terms of V and R ?
10.
